Re: Data Queue

["John Taylor" <jtaylor@xxxxxxxxxxxx>]

Mark,

I use this approach in some custom "wizards" I've created for retrieving
data from the 400.  The client creates the data queue, calls an RPG program
to populate it, processes the resulting records, then deletes the queue as
part of a cleanup process. The time it takes to create the queue is measured
in milliseconds, and isn't even worth worrying about when you consider the
overall processing time required to transfer the records. Of course, this
assumes that you're transferring dozens of records (or more) at a time. I
certainly wouldn't use this approach for something like a lookup function
which only returns a single record, yet is called many times.


Regards,

John Taylor
